T0 @ZZ Luiz/0m it may con/cern:

Be it known that we, ANDREW J. Ross and MARSHALL J. MORTON, citizens of the United States of America, and residents of Pioneer, county of Kern, State of California, have invented certain new and useful Improvements in Pumps, of which the following is a full and clear speciiication, reference being had to the accompanying drawings, in whiche- Figure 1 is a side elevation, and Fig. 2 a plan view, of our improved ump; Figs. 3, 4, and 5, vertical longitudina sectional views showing the oscillating cylinder in different positions Fig. 6, a vertical transverse section on the line 6 6 of Fig. 1 Fig. 7, a vertical section on the line 7 7 of Fig. 3; Figs. 8, 9, and 10, details showing more particularly the arrangement Of ports.

The object of this invention is to provide a simple and powerful apparatus which will furnish a continuous stream of water at a high pressure, as more fully hereinafter set forth.

To the accomplishment of this object and such others as may hereinafter appear the in vention consists of the arts and combination of parts hereinafter fully described, and particularly pointed out in the appended claims, reference being had to the accompanying drawings,forming a part of this speciiication, in which the same reference characters designate like parts throughout the several views.

Referring to the drawings by reference characters, A designates a double Y umpcyl inder mounted to oscillate upon a orizontal transverse bolt 1, which passes through a partition a at the center of the cylinder and through supporting-disks E E and is provided with a tightening-nut 2, said disks being stationarily mounted upon pedestals S, to which they are rigidly secured by bolts s. The disk E is provided with a central bolthole e5 and with segmental ports e3 e4, and the disk E is provided with a central bolt-hole e6 and a similar pair of ports e and e2. The ports in disk E are just below the horizontal center of the disk, while the ports in the disk E are just above the center.

Bolted to the outer face of disk E is a chamber F, adapted to be connected by its Y elbow f to a supply-pipe or a delivery-pipe and provided with iianges f3, by which it 1s bolted to the face of the disk over the ports e3 and e4, this chamber being provided with a recess or depression f4 in order to straddle the nut 2. Bolted to the outer face of the disk E is a similar casing F', which is provided with a recess f5 to straddle the head of bolt l, flangesf, by which it is bolted to the disk, and an elbow part f by which it is connected to the delivery or the supply pipe, according as this chamber is used as an exhaust or a supply chamber. This chamber F connects with the ports e/ and e2. Mounted to turn on the disks E E are a pair of similarlyshaped disks D D', hanged at d and d1", re-

spectively, to embrace the stationary disks,y

and provided with central holes d7 d8, respectively, for the passage of the central bolt 1. These disks D and D are grooved to receive the cylinder A and are clamped thereon by four transverse double-ended bolts The cylinder A is provided with segmental ports a3 and a5 at one side of the partition a and with similar ports a2 at the opposite side of the partition a. The ports a3 a5 register With ports d (Z2 in the oscillating disks, and when the cylinder is oscillated these ports are adapted to alternately register with the ports e2 e3 in the stationary disks. The corresponding ports a2 in the cylinder register with ports d2 in the oscillating disks, and these ports d2 are adapted to alternately register with the ports e e4 when the cylinder is oscillated. The cylinder is provided at each end with a stuffing-box a, and working in each end of the cylinder through its stufIing-box is a ram-piston B. These two pistons are connected to work in unison by cross-heads b b and connecting-rods b2. Attached to one of the pistons is a bracket-bearing c2, in which is journaled a crank-pin carried by a crank c', this crank being carried by a shaft c, journaled in bearings m of a pair of pedestals M, said shaft carrying a driving-pulley O or other means for driving it.

It will be observed that when the shaft c is driven the pistons will be alternately forced in and drawn out of the opposite ends of the cylinder and the cylinder will be oscillated to permit these movements of the pistons. The oscillation of the cylinder will cause the ports to alternately register with the inlet and outlet chambers, thereby alternately iilling and discharging the cylinders, keeping up a continuous discharge of liquid. This pump,

as will be observed, is especially adapted for use where a large supply under a powerful head is desired.

It will be apparent. to those skilled in the art that various mechanical embodiments of IIO the invention are possible, and we therefore do not wish to be limited to the exact arrangement and construction shown.

What we claim, and desire to secure by Letters Patent, is-

1. [nv an apparatus-of the class described, the combination of a pair of supporting-disks Stationarily mounted and provided each with a pair of inlet-ports, one pair being above the center and the other below, an oscillating disk mounted on each of said stationary disks, a double-ended cylinder mounted between said oscillating disks and divided mid- Way its ends by a single imperforate partition, the cylinder and oscillating disks being provided with ports adapted to alternately register with the ports in the stationary disks, the ports in the cylinder being at opposite sides of the same and also on opposite sides of said partition, a piston working in 'each end of the cylinder, means connecting these pistons, and means for oscillating the cylinder and reciprocating the pistons, substantially as set forth.

2. In a pump the combination of an oscillating double-ended cylinder having an imperforate partition midway its ends, means for pivotally supporting the cylinder, a piston working in each end of the cylinder, means connecting these pistons, means for reciprocating the pistons simultaneously in opposite directions and simultaneously oscillating the cylinder, and supply and exhaust 3. The combination of a pair of supporting-disks each provided with a pair of ports,

the ports in one disk being above the center and tlie ports in the other disk being below the center, an oscillating disk mounted on each of said stationary disks and provided with a pair of ports adapted to register with the ports in the stationary disk, a doubleended cylinder mounted between said oscillating disks and divided midway its ends with an imperforate partition, the cylinder and oscillating disks being provided with portsadapted to alternately register with the ports in the stationary disk, means connecting the oscillating disks to'clamp the same upon the cylinder, a piston working in each end of the cylinder, means connecting these pistons, and means for oscillating the cylinder and simultaneously reciprocating the pistons.

In testimony whereof we hereunto affix our signatures, in the presence of two wite nesses, this 28th day of JulyI 1905.
